You can see moisture freezing onto those plant stems. Temp is below 10F
Warm exhaust makes a bare spot on the ground below.
Moisture freezing on the bush to the right which is over 10 ft away. sort of like hoar frost.
Picture with furnace running so you can see the steam.
In windless condition, the steam goes everywhere. Tends to flow right because the AC blocks the left side.
Added another shroud over the intake pipe. This might decrease the number of ice crystals entering the intake without restricting the air flow. Plus when there is a blizzard coming from the right side, less snow will enter the intake opening.
I might try a length of black perforated drain pipe, maybe 4 ft. That would create a protected zone to suck air from. Unrestricted, but decrease the number of ice crystals and snow entering the intake opening. The black pipe might get heated by sunshine and help evaporate snow and ice that gets into the pipe.
